Hierarchical Relaxation in Large-twist-angle Moire Drives Supermoire Formation
Chuqiao Shi, Giovanny Espitia, Yanxing Li +9
Supermoire lattices in large-angle twisted bilayers have recently been shown to emerge from periodic arrangements of commensurate stacking motifs, yet the microscopic structural me…
Engineering Grain Boundary Commensurability for Ferroelectric Stabilization in Hafnia-Based Films
Chuqiao Shi, Xinyan Li, Xing He +11
Grain boundaries fundamentally dictate the macroscopic properties of polycrystalline materials by breaking long-range symmetry. In ferroelectrics, these structural discontinuities…
Revealing Atomic-Scale Switching Pathways in van der Waals Ferroelectrics
Xinyan Li, Kenna Ashen, Chuqiao Shi +9
Two-dimensional van der Waals (vdW) materials hold the potential for ultra-scaled ferroelectric (FE) devices due to their silicon compatibility and robust polarization down to atom…
Robust Super-Moiré in Large Angle Single-Twist Bilayers
Yanxing Li, Chuqiao Shi, Fan Zhang +19
Forming long wavelength moiré superlattices (MSL) at small-angle twist van der Waals (vdW) bilayers has been a key approach to creating moiré flat bands. The small-angle twist, how…
Preserving Surface Strain in Nanocatalysts via Morphology Control
Chuqiao Shi, Zhihua Cheng, Alberto Leonardi +4
Engineering strain critically affects the properties of materials and has extensive applications in semiconductors and quantum systems. However, the deployment of strain-engineered…
Uncovering Material Deformations via Machine Learning Combined with Four-Dimensional Scanning Transmission Electron Microscopy
Chuqiao Shi, Michael C. Cao, Sarah M. Rehn +5
Understanding lattice deformations is crucial in determining the properties of nanomaterials, which can become more prominent in future applications ranging from energy harvesting…
Deep Learning Enabled Strain Mapping of Single-Atom Defects in 2D Transition Metal Dichalcogenides with Sub-picometer Precision
Chia-Hao Lee, Abid Khan, Di Luo +9
2D materials offer an ideal platform to study the strain fields induced by individual atomic defects, yet challenges associated with radiation damage have so-far limited electron m…
